      <pre class="doc-comment">/**
 * \brief      This function performs an ARIA-CTR encryption or decryption
 *             operation.
 *
 *             This function performs the operation defined in the \p mode
 *             parameter (encrypt/decrypt), on the input data buffer
 *             defined in the \p input parameter.
 *
 *             Due to the nature of CTR, you must use the same key schedule
 *             for both encryption and decryption operations. Therefore, you
 *             must use the context initialized with mbedtls_aria_setkey_enc()
 *             for both #MBEDTLS_ARIA_ENCRYPT and #MBEDTLS_ARIA_DECRYPT.
 *
 * \warning    You must never reuse a nonce value with the same key. Doing so
 *             would void the encryption for the two messages encrypted with
 *             the same nonce and key.
 *
 *             There are two common strategies for managing nonces with CTR:
 *
 *             1. You can handle everything as a single message processed over
 *             successive calls to this function. In that case, you want to
 *             set \p nonce_counter and \p nc_off to 0 for the first call, and
 *             then preserve the values of \p nonce_counter, \p nc_off and \p
 *             stream_block across calls to this function as they will be
 *             updated by this function.
 *
 *             With this strategy, you must not encrypt more than 2**128
 *             blocks of data with the same key.
 *
 *             2. You can encrypt separate messages by dividing the \p
 *             nonce_counter buffer in two areas: the first one used for a
 *             per-message nonce, handled by yourself, and the second one
 *             updated by this function internally.
 *
 *             For example, you might reserve the first 12 bytes for the
 *             per-message nonce, and the last 4 bytes for internal use. In that
 *             case, before calling this function on a new message you need to
 *             set the first 12 bytes of \p nonce_counter to your chosen nonce
 *             value, the last 4 to 0, and \p nc_off to 0 (which will cause \p
 *             stream_block to be ignored). That way, you can encrypt at most
 *             2**96 messages of up to 2**32 blocks each with the same key.
 *
 *             The per-message nonce (or information sufficient to reconstruct
 *             it) needs to be communicated with the ciphertext and must be unique.
 *             The recommended way to ensure uniqueness is to use a message
 *             counter. An alternative is to generate random nonces, but this
 *             limits the number of messages that can be securely encrypted:
 *             for example, with 96-bit random nonces, you should not encrypt
 *             more than 2**32 messages with the same key.
 *
 *             Note that for both stategies, sizes are measured in blocks and
 *             that an ARIA block is 16 bytes.
 *
 * \warning    Upon return, \p stream_block contains sensitive data. Its
 *             content must not be written to insecure storage and should be
 *             securely discarded as soon as it's no longer needed.
 *
 * \param ctx              The ARIA context to use for encryption or decryption.
 *                         This must be initialized and bound to a key.
 * \param length           The length of the input data \p input in Bytes.
 * \param nc_off           The offset in Bytes in the current \p stream_block,
 *                         for resuming within the current cipher stream. The
 *                         offset pointer should be \c 0 at the start of a
 *                         stream. This must not be larger than \c 15 Bytes.
 * \param nonce_counter    The 128-bit nonce and counter. This must point to
 *                         a read/write buffer of length \c 16 bytes.
 * \param stream_block     The saved stream block for resuming. This must
 *                         point to a read/write buffer of length \c 16 bytes.
 *                         This is overwritten by the function.
 * \param input            The buffer holding the input data. This must
